Hero Updates

Talents

Level 10

Flailing Swipe [R1]

Cooldown reduced from 80 to 60 seconds.

Mana cost reduced from 80 to 60.

Level 20

Controlled Chaos [R1]

Cooldown of Flailing Swipe changed from 30 to 25 seconds.

Mana cost of Flailing Swipe changed from 30 to 25.

Developer Comment: We're buffing Flailing Swipe to be a more viable
option compared to Massive Shove. With this reduced cooldown, Stukov should
feel more free to peel for his teammates between team fights without risking
Flailing Swipe being on cooldown during the next engagement.

2019-05-22 Balance Update v 2.45.1

Hero Updates

Additional functionality: Also reduces the cooldowns of Stukov's Basic Abilities by 1.5 seconds

Level 13

It Hungers [E]

Enemy Heroes hit required reduced from 12 to 10

Poppin' Pustules [Trait]

Additional functionality: Enemies hit by the explosion also have a Weighted Pustule applied to them

Level 16

Universal Carrier [Q]

Healing reduction on Healing Pathogen reduced from 50% to 40%

Developer Comment: We're making some quality of life changes to some of
Stukov's talents to make them better. Targeted Excision in particular suffered
from some awkwardness where when used properly, the cooldown of Bio-Kill
Switch would often be lower than the cooldowns of his Healing Pathogen and
Weighted Pustule, which made part of its benefit meaningless. This change
should make its 5-second cooldown more important, as he can use his other
abilities sooner after his initial cast of Bio-Kill Switch.

2019-04-17 Balance Update v 2.44.1

Hero Updates

Talents

We've adjusted Stukov's Level 1 talents to be positioned in the same order as other heroes (ex. Q talents on top, then W then E)

Level 1

Reactive Ballistospores (W)

Moved from Level 13

Cooldown increased from 10 to 15 seconds

Level 4

Biotic Armor (Q)

Armor bonus when detonating Bio-Kill switch increased from 50 to 75

Level 10

Flailing Swipe (R1)

Mana cost reduced from 100 to 80

Level 13

Poppin' Pustules (Trait)

Moved from Level 1

Damage bonus increased from 100% to 150%

Developer Comment: In order to improve the pick and win rates of
Reactive Ballistospores and Poppin' Pustules, we're switching the talents with
one another. This should open up new talent synergy possibilities for Poppin'
Pustules and offer the considerable strength of Reactive Ballistospores
earlier in the game. We're also buffing Biotic Armor to be a fairly
significant Physical Armor buff when Bio-Kill Switch is activated, which
should make its moment of power feel much more meaningful.

Developer Comment: As we promised in the past, we took a look at the
overall Mana tension of all the Heroes in the game. We also have some
philosophies about Mana that we want to keep going forward. They are:

Mana should be a meaningful part of the game, particularly in the early
stages when wave clear is at a higher premium. We believe that as the game
progresses, Mana tension should become less important as Heroes gain more base
Mana and the game's focus shifts to team fighting.

Mana tension doesn't have to be the same for every Hero, but every Hero
should feel it to some degree, otherwise it serves no purpose.

We like that some talents heavily mitigate Mana tension.

When we took a look at Mana tension in the game, we saw that, overall,
things are in a fairly healthy spot, but could be fine-tuned and improved
upon. We like the tension that the heroes who are closer to the middle of the
spectrum have, with some examples being Malfurion, Tychus, and E.T.C. Our goal
with these changes is to bring the outliers closer to the center. We are open
to your feedback going forward if you think that the game needs to be stricter
or more lenient in this area, or if you believe there are any outliers that we
missed.

Abilities

Lurking Arm (E)

Range increased from 10 to 11

Developer Comment: Stukov's changes a few months ago were intended to
create new build paths while also reducing the dominance of his Lurking Arm
build. While this had the effect we intended, Lurking Arm is now a much more
risky ability to use for the majority of the game, whether or not he takes
talents related to improving the ability. This change is intended to round
this out a bit by letting Stukov use Lurking Arm a little more safely.

2018-11-13 Patch Notes v 2.40.0

Stukov: Fixed an issue preventing Lurking Arm from revealing damaged targets if they were at the edge of its area of effect.

Top Off (Q)

Moved from Level 4

Bonus healing reduced from 50% to 30%

Adjusted Functionality:

Increased healing is now applied to all targets that have Healing Pathogen

Developer Comment: In the same vein as our earlier changes to Kael'thas,
we felt that Stukov could use some love in the talent diversity department.
We've made a number of functionality changes that should open up new builds
and play styles, particularly in his earlier talent tiers.

Bug Fixes

Stukov: Fixed an issue that could prevent Virulent Reaction from rooting targets if the Poppin Pustules talent was chosen.

Bug Fixes

Stukov: Stop, Hold Fire, Taunt, and Dance commands can no longer be issued while casting or channeling Lurking Arm.
